Description

Technical Field

[0001] The invention relates to the technical field of round bottle labeling, in particular to a full-automatic round bottle labeling machine. Background Art

[0002] The fully automatic round bottle labeling machine is suitable for labeling the circumference of round bottle-like objects. It is a device that uses adhesive to stick paper or metal foil labels on specified packaging containers. It is widely used in cosmetics, food, medicine, disinfectant and other industries. Labeling machines are an indispensable part of modern packaging. At present, the types of labeling machines produced in my country are gradually increasing, and the technical level has also been greatly improved.

[0003] In the existing fully automatic round bottle labeling machine, during the labeling process, due to the exposed working environment and the large differences in the labeling processing environment of different factories, dust and particles sometimes adhere to the bottle during the labeling process. These dust and particles will form a gap between the bottle and the label, resulting in a reduction in the area of direct contact between the label and the bottle, thereby reducing the adhesion between the label glue and the bottle, which can easily cause the label to warp or fall off during transportation, storage or use;

[0004] In addition, during the labeling process of round bottles, if the pressure of the labeling head of the labeling machine is insufficient, the label will not be able to fit well with the bottle body, and the label will not be tightly pasted. Not only will the corners of the label be easily lifted up, causing the label to fall off, but it will also cause the label to be unevenly pasted, thereby reducing the labeling work quality of the labeling machine. In view of this, we propose a fully automatic round bottle labeling machine. Summary of the invention

[0005] The object of the present invention is to provide a fully automatic round bottle labeling machine to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides a fully automatic round bottle labeling machine, including a machine body, a bracket fixedly connected to the machine body, a labeling mechanism provided on the bracket for labeling round bottles, a dust cleaning mechanism provided on the labeling mechanism, the position of the round bottle to be labeled is wiped by the dust cleaning mechanism, and a pressing mechanism is provided on the labeling mechanism, and the label can be pressed by the pressing mechanism after the round bottle is labeled.

[0007] As a further improvement of the technical solution, the labeling mechanism includes fixed blocks fixedly connected to both sides of the bracket, the fixed blocks are fixedly connected to pillars, and the pillars are rotatably connected to rotating plates.

[0008] As a further improvement of the technical solution, the dust cleaning mechanism at least includes a plurality of mounting blocks fixedly connected to the rotating plate. A connecting rod is fixedly connected between every two mounting blocks. A first telescopic rod is fixedly connected to each connecting rod. A dust removal roller is rotatably connected between the two first telescopic rods.

[0009] As a further improvement of the technical solution, the pressing mechanism at least includes a U-shaped plate fixedly connected to the fixed block. Two second telescopic rods are rotatably connected to the U-shaped plate. A pressing roller is rotatably connected between the two second telescopic rods. Two limiting rods are rotatably connected to one side of the rotating plate close to the second telescopic rods, and the other sides of the limiting rods away from the rotating plate are respectively rotatably connected to one side of the adjacent second telescopic rods.

[0010] As a further improvement of the technical solution, two groups of the dust cleaning mechanisms are provided and symmetrically arranged on the two rotating plates.

[0011] As a further improvement of the technical solution, support plates are fixedly connected to both of the fixed blocks. Two first return springs are fixedly connected to one side of the support plates close to the rotating plate, and the other sides of the first return springs away from the support plates are fixedly connected to one side of the rotating plate.

[0012] As a further improvement of the technical solution, a second return spring is fixedly connected to the inner cavity of the first telescopic rod, and the other side of the second return spring is fixedly connected to one side of the extending end of the connecting rod. A third return spring is fixedly connected to the inner cavity of the second telescopic rod, and the other side of the third return spring is fixedly connected to one side of the extending end of the second telescopic rod;

[0013] The spring coefficients of the second return spring and the third return spring are smaller than the spring coefficient of the first return spring.

[0014] As a further improvement of the technical solution, a conveyor belt is sleeved on the support, and the conveyor belt is located below the rotating plate.

[0015] As a further improvement of the technical solution, L-shaped plates are fixedly connected to both sides of the support. Hydraulic rods are fixedly installed on the L-shaped plates. A blocking plate is slidably connected to the conveyor belt, and the output end of the hydraulic rod is fixedly connected to the blocking plate.

[0016] Compared with the prior art, the beneficial effects of the present invention:

[0017] 1. In this fully automatic round bottle labeling machine, the round bottle squeezes the dust removal roller, and with the elastic movement of the first telescopic rod, the contact surface between the dust removal roller and the round bottle can be closely attached. During the movement of the round bottle and the extrusion of the dust removal roller, the dust removal roller can wipe the position of the round bottle where the label will be pasted, providing a clean and smooth pasting surface for the label, enabling the label to be more smoothly attached to the bottle body during pasting, and avoiding problems such as bubbles and wrinkles.

[0018] 2. In this fully automatic round bottle labeling machine, when the round bottle gradually passes through between the rotating plates, through the elastic movement of the rotating plates, in cooperation with the limit rod, the second telescopic rod, etc., the pressing roller is driven to abut against the round bottle. When the pressing roller moves in an arc during reset, it can press the label position of the round bottle, effectively exhausting the air between the label and the bottle body, making the label closely attached to the bottle body. This closely attached state can reduce the generation of bubbles and wrinkles, making the label pasted more smoothly and firmly, greatly improving the quality of labeling.

[0019] 3. In this fully automatic round bottle labeling machine, through the rotation of the rotating plates, in cooperation with the mounting block and the connecting rod, etc., the dust removal roller is driven to rotate. Through the elastic movement of the dust removal roller, an additional supporting force can be provided to the round bottle, so that the round bottle will not easily shake or shift during the labeling process, which is beneficial for the label to be smoothly and firmly attached to the bottle body, further improving the labeling quality; when the rotating plate does not move, while the dust removal roller wipes and removes dust from the bottle body, it can play a certain role in limiting and guiding the bottle, thus ensuring that the position of the bottle is relatively stable and centered during transmission, which helps the accuracy of subsequent labeling operations.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0036] Please refer to Figures 1 - 8 As shown in the figure, this embodiment provides a fully automatic round bottle labeling machine, including a body 100. A bracket 110 is fixedly connected to the body 100. A labeling mechanism 200 is provided on the bracket 110 for labeling round bottles. A dust cleaning mechanism 300 is provided on the labeling mechanism 200. By wiping the position of the round bottle to be labeled through the dust cleaning mechanism 300, dust and impurities adhering to the bottle body can be removed, avoiding the occurrence of bubbles or wrinkles during the pasting process of the label due to the presence of dust and impurities, which affects the aesthetics and flatness of the labeling effect. A pressing mechanism 400 is provided on the labeling mechanism 200;

[0037] During the process of providing guiding support force to the round bottle by the ash cleaning mechanism 300 through elastic movement, the position of the round bottle where the label is about to be pasted is wiped; during the arc-shaped movement of the pressing mechanism 400 to adapt to the pressing of the outer wall of the round bottle, after the label is pasted on the round bottle, the pressing mechanism 400 can press the label. Since there may be some tiny gaps between the label and the bottle body after the label is pasted on the round bottle, resulting in insufficient firm adhesion of the label, by pressing the label through the pressing mechanism 400, the label can be more closely attached to the bottle body, eliminating these gaps, thereby enhancing the adhesion between the label and the bottle body.

[0038] In consideration of the existing fully automatic round bottle labeling machine, during the labeling process, due to the exposed working environment and significant differences in the labeling processing environments of different factories, in such cases, dust and particles sometimes adhere to the bottle body during labeling processing. These dust and particles will form intervals between the bottle body and the label, resulting in a reduction in the direct contact area between the label and the bottle body, and further reducing the bonding force between the label glue and the bottle body, which easily leads to the phenomenon of the label warping or falling off during transportation, storage, or use; therefore, the ash cleaning mechanism 300 is provided. Before the round bottle is labeled, it will first pass through the ash cleaning mechanism 300. When the round bottle moves while squeezing the ash cleaning mechanism 300 and driving the ash cleaning mechanism 300 to move elastically, the ash cleaning mechanism 300 can always be closely attached to the contact surface of the round bottle, and then wipe the position of the round bottle where the label is about to be pasted, providing a clean and smooth pasting surface for the label, enabling the label to be more smoothly attached to the bottle body during pasting, and avoiding problems such as air bubbles and wrinkles.

[0039] Also considering that during the labeling process of the round bottle, if the labeling head pressure of the labeling machine is insufficient, the label cannot be well attached to the bottle body, and the situation of loose adhesion will occur. This will not only make the corners of the label easy to warp and then cause the label to fall off, but also result in uneven pasting of the label, thereby reducing the labeling work quality of the labeling machine; therefore, the labeling mechanism 200 and the pressing mechanism 400 are provided. When the round bottle squeezes the labeling mechanism 200 and drives the labeling mechanism 200 to move elastically, the labeling mechanism 200 drives the pressing end of the pressing mechanism 400 to move. When the pressing end of the pressing mechanism 400 moves in an arc shape, it can press the label area of the round bottle, effectively exhausting the air between the label and the bottle body, making the label closely attached to the bottle body. This closely attached state can reduce the generation of air bubbles and wrinkles, making the label pasted more smoothly and firmly, greatly improving the labeling quality.

[0040] Furthermore, when the labeling mechanism 200 moves, it can drive the dust cleaning mechanism 300 to move. Through the elastic movement of the dust cleaning end of the dust cleaning mechanism 300, an additional supporting force can be provided to the round bottle, so that the round bottle will not shake or shift easily during the labeling process, which is conducive to the label being smoothly and firmly pasted on the bottle body, further improving the labeling quality. When the dust cleaning mechanism 300 does not move, while wiping and removing dust from the bottle body, the dust cleaning mechanism 300 can play a certain role in limiting and guiding the bottle, so as to ensure that the position of the bottle is relatively stable and centered during transmission, which helps to improve the accuracy of subsequent labeling operations.

[0041] Considering that it is necessary to label round bottles, as Figure 2 and Figure 3 shown, the specific structure of the labeling mechanism 200 is further disclosed. The labeling mechanism 200 includes fixing blocks 210 fixedly connected to both sides of the bracket 110. Support columns 220 are fixedly connected to the fixing blocks 210. Rotating plates 221 are rotatably connected to the support columns 220. When the round bottle moves, it squeezes the rotating plates 221, driving the two rotating plates 221 to open outward. While the round bottle squeezes the rotating plates 221, the label on the rotating plates 221 can be pasted onto the bottle body to achieve the labeling process.

[0042] Before labeling the round bottle, first wipe the labeling area of the round bottle to make the label stick more smoothly. As Figure 3 shown, the specific structure of the dust cleaning mechanism 300 is further disclosed. The dust cleaning mechanism 300 at least includes a plurality of mounting blocks 310 fixedly connected to the rotating plate 221. Connecting rods 311 are fixedly connected between every two mounting blocks 310. First telescopic rods 312 are fixedly connected to the connecting rods 311. A dust removal roller 313 is rotatably connected between the two first telescopic rods 312. When the round bottle passes by the dust removal roller 313, it squeezes the dust removal roller 313, driving the first telescopic rods 312 to contract. During the process of the round bottle moving and squeezing the dust removal roller 313, the dust removal roller 313 can wipe the position of the round bottle where the label will be pasted, providing a clean and smooth pasting surface for the label, so that the label can fit more smoothly on the bottle body when pasted, avoiding problems such as air bubbles and wrinkles.

[0043] After the round bottle is labeled, in order to make the label adhere more firmly to the bottle body, as Figures 4 - 5 and Figures 7 - 8As shown in the figure, the specific structure of the pressing mechanism 400 is further disclosed. The pressing mechanism 400 at least includes a U-shaped plate 410 fixedly connected to the fixed block 210. Two second telescopic rods 411 are rotatably connected to the U-shaped plate 410. A pressing roller 412 is rotatably connected between the two second telescopic rods 411. Two limiting rods 413 are rotatably connected to one side of the rotating plate 221 close to the second telescopic rod 411, and the other sides of the limiting rods 413 away from the rotating plate 221 are respectively rotatably connected to one side of the adjacent second telescopic rod 411. As shown by the arrow a, when the rotating plate 221 rotates and opens, it drives the limiting rod 413 to move, thereby driving the second telescopic rod 411 to rotate on the U-shaped plate 410. When the round bottle gradually passes through between the rotating plates 221, through the elastic reset movement of the rotating plate 221, the limiting rod 413 is pulled to move, thereby driving the limiting rod 413 to reset and move, and further driving the pressing roller 412 to move. At this time, the pressing roller 412 abuts against the round bottle. When the second telescopic rod 411 drives the pressing roller 412 to reset and move in an arc, it can drive the pressing roller 412 to press the label of the round bottle, effectively exhausting the air between the label and the bottle body, making the label closely fit the bottle body, making the label stick more smoothly and firmly, and improving the labeling quality.

[0044] Considering that the round bottle needs to be centered during labeling, as Figure 3 shown in the figure, two sets of dust cleaning mechanisms 300 are provided and symmetrically arranged on the two rotating plates 221. By setting two sets of dust cleaning mechanisms 300, since the two dust removal rollers 313 are symmetrically arranged, when the round bottle is conveyed, by squeezing the dust removal rollers 313, while the dust removal rollers 313 wipe and remove dust from the bottle body, they can play a certain role in limiting and guiding the bottle, so as to ensure that the position of the bottle is relatively stable and centered during conveyance, which helps to improve the accuracy of subsequent labeling operations; and when the round bottle squeezes the rotating plate 221 and drives the rotating plate 221 to rotate, the rotating plate 221 drives the mounting block 310, the connecting rod 311 and the dust removal roller 313 to rotate. Under the elastic action of the second return spring 320, the dust removal roller 313 can be driven to abut against one side of the round bottle, so that during the labeling process of the round bottle, the dust removal roller 313 can provide an additional supporting force for the round bottle, so that the round bottle will not easily shake or shift, which is beneficial to the label being smoothly and firmly pasted on the bottle body, and further improves the labeling quality.

[0045] After the round bottle moves out between the two rotating plates 221, it is necessary to drive the rotating plate 221 to reset and move, as Figure 3As shown, support plates 500 are fixedly connected to both of the two fixed blocks 210. On the side of the support plate 500 close to the rotating plate 221, two first return springs 510 are fixedly connected, and the side of the first return spring 510 away from the support plate 500 is fixedly connected to one side of the rotating plate 221. When the round bottle gradually moves out from the narrow opening of the rotating plate 221, under the force of the first return spring 510 restoring deformation, it drives the rotating plate 221 to move back to prepare for the next labeling. And when the rotating plate 221 moves back, it drives the limiting rod 413 in the pressing mechanism 400 to move, thereby driving the second telescopic rod 411 to move, and further driving the pressing roller 412 to move, so that the pressing roller 412 abuts against the round bottle. When the pressing roller 412 moves back in an arc, it can press the label position of the round bottle.

[0046] Considering that this device can clean and press round bottles with different diameters, as Figure 5 and Figure 6 shown, a second return spring 320 is fixedly connected to the inner cavity of the first telescopic rod 312, and the other side of the second return spring 320 is fixedly connected to one side of the extending end of the connecting rod 311. By setting the second return spring 320, when round bottles with different diameters squeeze the dust removal roller 313, it can drive the first telescopic rod 312 to contract, so as to realize wiping different diameters of round bottles. A third return spring 420 is fixedly connected to the inner cavity of the second telescopic rod 411, and the other side of the third return spring 420 is fixedly connected to one side of the extending end of the second telescopic rod 411. By setting the third return spring 420, different diameters of round bottles squeeze the pressing roller 412, driving the second telescopic rod 411 to contract to different degrees, so as to press the labels adhered to round bottles with different diameters;

[0047] The spring coefficients of the second return spring 320 and the third return spring 420 are smaller than the spring coefficient of the first return spring 510. When the round bottle squeezes the dust removal roller 313 or the pressing roller 412, since the spring coefficients of the second return spring 320 and the third return spring 420 are both smaller than the spring coefficient of the third return spring 420, the round bottle squeezing the dust removal roller 313 drives the first telescopic rod 312 or the second telescopic rod 411 to contract, avoiding the movement of the rotating plate 221 when the dust removal roller 313 cleans the bottle body.

[0048] Considering that the conveyed round bottles need to be processed, as Figure 2 shown, a conveyor belt 111 is sleeved on the bracket 110, and the conveyor belt 111 is located below the rotating plate 221. A control motor is fixedly installed on one side of the conveying roller of the conveyor belt 111. Starting the control motor drives the conveyor belt 111 to drive, and drives the round bottles on the conveyor belt 111 to move.

[0049] Considering that when the round bottle moves on the conveyor belt 111, in order to limit it, as Figure 1As shown in the figure, L-shaped plates 600 are fixedly connected to both sides of the bracket 110. Hydraulic rods 610 are fixedly installed on the L-shaped plates 600. A baffle 611 is slidably connected to the conveyor belt 111, and the output end of the hydraulic rod 610 is fixedly connected to the baffle 611. By starting the hydraulic rod 610 to drive the baffle 611 to move, according to the diameter of the round bottle, it is limited, reducing the situation of shaking and displacement of the round bottle during transmission on the conveyor belt 111, and improving the accuracy of the round bottle during subsequent labeling.

[0050] Working principle: Place the round bottle to be labeled on the conveyor belt 111. Pass the label tape through the rotating plate 221 near the U-shaped plate 410, and the label tape is located between the two first telescopic rods 312. Then start the driving device connected to the conveyor belt 111 to drive the conveyor belt 111 to rotate, thereby driving the round bottle on the conveyor belt 111 to rotate. When the round bottle passes through the dust removal roller 313, it squeezes the dust removal roller 313, driving the first telescopic rod 312 to contract, thereby compressing the second return spring 320, causing the second return spring 320 to deform. During the process of the round bottle moving while squeezing the dust removal roller 313, the dust removal roller 313 can wipe the position of the round bottle where the label will be pasted, providing a clean and smooth pasting surface for the label, enabling the label to fit more smoothly on the bottle body during pasting, and avoiding problems such as air bubbles and wrinkles.

[0051] The wiped round bottle continues to move, squeezing the rotating plate 221, driving the two rotating plates 221 to open outward. At this time, the first return spring 510 is compressed and deformed. When the round bottle squeezes the rotating plate 221, the label on the rotating plate 221 can be pasted on the bottle body to achieve the labeling process.

[0052] As shown by arrow a, while the rotating plate 221 rotates and opens, in cooperation with the limiting rod 413, it drives the second telescopic rod 411 to rotate on the U-shaped plate 410. When the round bottle gradually passes through between the rotating plates 221, under the force of the first return spring 510 restoring deformation, it drives the rotating plate 221 to move back, thereby pulling the limiting rod 413 to move, and further pulling the limiting rod 413 to move back. The movement of the limiting rod 413 drives the pressure roller 412 to move. At this time, the pressure roller 412 abuts against the round bottle. When the second telescopic rod 411 drives the pressure roller 412 to move back in an arc, it can drive the pressure roller 412 to press the label of the round bottle, effectively exhausting the air between the label and the bottle body, making the label fit tightly with the bottle body. This tight fit can reduce the generation of air bubbles and wrinkles, making the label pasted more smoothly and firmly, and improving the quality of labeling.

[0053] While the rotating plate 221 rotates, it drives the mounting block 310 to rotate and cooperates with the connecting rod 311 to drive the dust removal roller 313 to rotate. Under the elastic action of the second return spring 320, the dust removal roller 313 can be driven to abut against one side of the round bottle, so that when the rotating plate 221 applies a label to the round bottle or the pressing roller 412 presses the label tightly, the dust removal roller 313 can provide an additional supporting force to the round bottle, so that when applying a label to the round bottle or when the pressing roller 412 applies pressure to the label, the round bottle will not shake or shift easily, which is beneficial to the label being adhered to the bottle body flatly and firmly, and further improves the labeling quality.

[0054] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only preferred examples of the present invention, and do not limit the present invention.
